The recall notice describes the fix as: that likely to be affected and check for seepage of brake fluid. If the brake fluid seepage is apparent the flexible brake hose and the associated metal brake pipes will be replaced. You won't usually pay for it.1
What’s Wrong
A seepage of brake fluid may occur at the union between the rear flexi hose and the metal brake pipes. This would eventually lead to the illumination of the low fluid warning lamp which if left would result in longer brake pedal travel and reduced effectiveness of the brakes.

Remedy: Recall the vehicles that likely to be affected and check for seepage of brake fluid. If the brake fluid seepage is apparent the flexible brake hose and the associated metal brake pipes will be replaced.
